USING FLEXIBLE VENT COMPONENTS
Use only approved fl exible vent pipe kits marked:
“Wolf Steel Approved Venting” as
identifi ed by the stamp only on the
7” fl exible vent pipe.
For safe and proper operation of the fi replace, follow the
venting instructions exactly.
All 4" fl exible vent pipe and 7" fl exible vent pipe joints
may be sealed using high temperature sealant W573-0002
(not supplied) or the high temperature sealant W573-0002
Mill Pac (not supplied). However, the high temperature
sealant W573-0007 Mill Pac (not supplied) must be used
on the joint connecting the 4" fl exible vent and the exhaust
fl ue collar.

FIGURE 31
Six inches (6”) is the minimum bend radius allowed for the
7” fl exible vent pipe.
Do not allow the 4" flexible vent pipe
to bunch up on horizontal or vertical
runs and elbows. Keep it pulled
tight. A 1 1/4” air gap between the 4"
and 7" flexible vent pipes all around
is required for safe operation. A
spacer is required at the start, middle
and end of each elbow to ensure this
gap is maintained. Spacers are
attached to the 4" flexible vent pipe
at predetermined intervals to
maintain a 1-1/4” air gap to the 7"
flexible vent pipe. These spacers
must not be removed.

1. Stretch the 4" fl exible vent pipe to the required length taking into
account the additional length needed for the fi nished wall surface.
Slip the vent pipe a minimum of 2" over the inner sleeve of the air
terminal and secure with 3 #8 screws. Apply a heavy bead of the high
temperature sealant W573-0007 (not supplied).
NOTE: If using pipe clamps to connect vent components, 3
screws must also be used to ensure the connection cannot slip
off.
2. Using the 7" fl exible vent pipe, slide over the outer combustion
air sleeve of the air terminal and secure with 3 #8 screws. Seal using
high temperature sealant W573-0002 (not supplied).
3. Insert the vent pipes through the fi restop maintaining the required
clearance to combustibles. Holding the air terminal (lettering in an
upright, readable position), secure to the exterior wall and make weather
tight by sealing with caulking (not supplied).
4. If more vent pipe needs to be used to reach the fi replace, couple them
together as illustrated. The vent system must be supported approximately
every 3 feet for both vertical and horizontal runs. Use noncombustible
strapping to maintain the minimum 1" clearance to combustibles.
The air terminal mounting plate may be recessed into the exterior wall
or siding by 1½", the depth of the return fl ange.
